Application filed May 15, 1914. Serial No. 838,782 e To aZZ whom it mayconcern:

jBe'it known that I, ARTHUR E. a citizen of the United States, residingat Vayne, in the county of Wayne and State of Nebraska, have inventedcertain new and useful Improvements inSpikes, of whlch the following isa specification. This invention relates to an improved spike and theprincipal object of the invention is to provide an improved means forlocking the spike ina tie, the spike be ng provided with a tapered pinreceiving pocket in which a pin may be placed to spread the arms of thespike and lock the spike.

Another object of the invention is to so construct the pocket that thesecuring pin may be easily driven into place after the spike has beendriven into the tie. p This invention is illustrated in the accompanyingdrawings, wherein- Figure 1 HALLADA before the securing pin is inserted;Fig. 2 is a view simliar to Fig. 1 with the securing pin inserted; Fig.3 is a vertical sectional view through the spike taken along the line 33in Fig. 2 with the securing pin in place and shown in elevation; andFig. {1, isa transverse sectional view taken along the line 1-4 ofFig. 1. I

' The spike 10-is split longitudinally to 11 which are provided withteeth 12 and have their lower end portions 13 tapered to form apenetrating point for the spike. Grooves are formed in the arms 11 thusforming a pocket 14: which tapers toward the penetrating endof thespike. It should be noted that by providing a groove instead of a slot awall will be provided at the inner end ofthe pocket.

After the spikehas been driven into the tie to such an extent that thehead 15 engages the rail base, the spreading finger or 16 is inserted inthe pocket 14: and

driven k 11 will bes'pread to the position shown. in Fig. 2. Itshould'be notedthat the lower end 17 of this wedge is rounded so thatthe wedge may be incline and then easily ing longitudinally ofthe armsis a rear elevation of the spike down into the same so that the armsplaced in the pocket at an driven downwardly to the position shown inFig. 3.

easily driven into place. i It should'be noted that byhaving the spikeformed of resilient mater1al that a binding action "is caused which w1llholdthe wedge; in place and prevent the lower end ofthewedge fromslipping out offthe pocket 14. when. driving the wedge downwardly. If'itis desired to remove the-spike, the head 18. may be engaged by! asuitable. moving tool and the. wedge ,withdrawn'from thepocket.The-spike can then be ren' ovedby a suitable moving tool.
